4 Claims. (Cl. 4252) This invention relates to improvements in water closet installations, and more particularly to an improved wall hung water closet and an improved carrier therefor.

it is now common practice in the industry to provide eitherV single or back-to-back wall hung water closet installations for both improved appearance and ease of cleaning the floor area around and beneath the bowl portion of the closet. However, very few, if any, basic structural changes have been made in such closet and carrier construction, aside from the rearrangement of the outlet in the bowl portion.

In accordance with prior art practice, such wall hung closet installations are generally of two types. In the first type, the bowl portion is supported on the wall by means of fasteners, such as bolts, extending through preformed openings in the bowl portion, while the flush tank portion is hidden from view within the wall itself. This type of construction is quite expensive, being diilicult to install and requiring a special carrier for the separate bowl and tank portions, unusually thick walls for containing the tank portion, as well as complicated( plumbing connections. Thus, as a practical matter, this type of closet installation is AlimitedV to non-residential buildings, except possibly luxury homes. Further, even though the tank portion be hidden from view, the protruding bolts from the carrier, at least two vertically spaced bolts being required on each side of the bowl portion, detract from the otherwise pleasing appearance of the bowl portionrby requiring an unnecessarily large panel portion at the rear thereof.

In the second type of closet installation which is more economical and better suited for residential use, but at the same time more cumbersome and less pleasing in appearance, the bowl portion is supported as described above, but isprovided with an extension at itsrear end, upon which a separate tank portion rests. For stability in such an installation, it is necessary to puncture the tank portion for the reception of fastening means, such as bolts, extending upwardly from the rear of the bowl' portion through the'bottom of the tank. This construction not only has many of the disadvantages of the rst type, but requires special gaskets to adequately seal the tank portion against leakage. In addition, these seals canjeasily be broken by a jarring of the tank portion, and gradually lose their eifectiveness as the gaskets deterioratevunder attack by the mineral contents of the water in the tank portion.

Moreover, in either type of prior art installation, the bottom of the tank is located above the rim of the bowl, whether the tank is in the wall or mounted on the bowl. Thus, if the bowl becomes fouled because the closet or soil lines are plugged up, the water head in the tank will cause the water in the bowl to flood over the rim when the iiush valve is opened by the lever. As will be apparent, this can not only cause inconvenience and damage to property but also can be a serious personal health problem,

Accordingly, it is a primary object of thisinvention to provide an improved wall hung water closet installa-V tion that overcomes the various disadvantages of the aforesaid prior art installations, by reason of the fact that it is economical to manufacture, easy to install, more pleasing in appearance, particularly adapted for use in single or back-to-back installations in residential construction, and so constructed and designed as to avoid overflow over the rim of the bowl should the closet or soil lines be plugged up.

A more specific object of the invention is to provide an improved wall hung water closet carrier adapted for use with conventional wall construction and incorporating bracket means for supporting the tank portionof the closet, thereby eliminating at least two of the fastening means, such as bolts, required by prior art installations, as well as the necessity for an'unduly large panel portion at the rear of theV closet.

Another more specilic object of the invention is to provide an improved wall hung water closet that is of one piece construction for economy of manufacture and improved appearance, wherein the bottom wall of the integral tank portion is arranged substantially below the` rim of the bowl portionto prevent overflow of water over the bowl rim even when the closet is flushed while the soil'or closet lines are plugged up, and wherein an integral panel portion is arranged at the rear of the ush tank and bowl portions, the panel portion being provided with iiange means adjacent the tank portion and engageable with the bracket means on the carrier, as well as means, such as upright slots, arranged below the flange means for receiving the lower fastening means on the carrier, thereby facilitating installation of the closet on the carrier, as well as eliminating any puncturing of the tank portion. t

Other objects and advantages of the invention will become apparent upon consideration of the following detailed description and accompanying drawings Wherein:

Fig. 6 is a partial vertical elevational View, similar to Fig. l, but illustrating partly in section, a back-to-back installation embodying the invention.

Referring to the drawings, wherein like numerals indicate like parts, and particularly Figs. 1-5, the single type Patented July 19, 1960 installation constituting an embodiment ofthe invention will now be described. The installation includes the yoke type carrier generally indicated at 6 and the one piece, wall Yhung closet generally indicated at.7.` The conventional construction for this installation includes a concrete slab floor 8 and aconcrete block wall 9 provided with a finished wall 10 of plaster or the like. As'will be apparent from Fig. 2, slab 8 is provided with an opening for the reception of the necessary plumbing connections including a lower stack 11, stack fitting 12, which is provided with the usual elbow 13 and vent 14, and the upper stack 15. As will also be apparent from Fig. 2, the wall 9 is provided with an opening for the reception ofthe aforesaid plumbing connections and carrier 6, and as yseen in Fig. 1, the installation is so designed that the closet 7 will fit substantially flush against the finished wall 10 when installed. As a practical matter, in order to prevent the closet from marring the finished wall, it is desired that the upper and lower mounting means for the closet be so arranged that when the closet is supported thereby a slight clearance ofsay 1/2 to 1A@ inch exists between the surface of the finished wall and the back surface of the closet.

As also seen in Fig. 4, the carrier 6 is composed of a base plate 16 which is secured to slab S by means of the usual anchor bolts 17 and nuts 18, and which is provided with a pair of laterally spaced upright plates 19. These upright plates are rigidly supported by means of the yoke plates 20 having L-shaped extensions 21 at their lower ends which are secured to base plate 16 by bolts 22 and upper curved portions 23 which are secured to the upper portions of upright plates 19 by bolts 24.

. The improvement in carrier 6 comprises the lateral bracket means which spans the upper ends of upright plates 19 and is `composed of a relatively wide and elongated laterally extending, upright plate 25 and a relatively narrow and elongated upright plate 26 abutting and preferably welded to plate 25 and provided with al pair of -laterally spaced lugs 27. These lugs extend outwardly and upwardly of the upper ends of upright platesA 19 from the adjacent side iof plate 25 toward its upper edge, and each of plates 25 and 26 are provided with openings for receiving the upper fastening means which extend outwardly from the upper ends of upright plates 19. This upper fastening means is preferably composed of bolts 28 secured to the upper endsof upper plates 19 by nuts 29 and provided with lock nuts 30 and 31 engageable with plates 25 and 26 respectively, for securing the bracket means in spaced relationship to upper plates 19 so that plate 25 will be substantially flush with finished wall 10.

VAt their lower ends, upright plates 19 are provided with lower fastening means preferably composed of bolts 32 secured thereto by nuts 33 and having lock nutsl 34, bearing washers 35, fiber washers 36, and cap nuts 37, all for a purpose to be described below. i

Referring once again to Figs. l, 2, 3 and 5 particularly, the one piece closet 7 embodying the invention is preferably composed of a tank portion 39 having the usual lid 40 and flushvalve operating lever 41, a bowl'porti-on 42 having a rearv outlet 43 (Fig. 5), and an integral panel portion 44 arranged at the rear of the tank portion 39 and bowl portion 42, all of which portions are economically cast in one piece and then fired in china. As best seen in Figs. 1 and 3, the panel portion 44 is provided with recess forming means at its upper end including a pair of laterally spaced and recessed upright wall portions 45 forming at least part of the rea-r wall of tank portion 39 and a lateral wall portion 46 extending outwardly from the upper ends of upright wall portions 45. In addition, fiange means preferably composed of a pair of laterally spaced flanges 47 corresponding to the spaced lugs 27, extend downwardly and outwardly of the rear of tankportion`39 from lateralrwall portion 46 toward its 4 outer end and into engagement between lugs 27 and plate 25. Arranged below flanges 47 on panel portion 44 are a pair of upright slots 48 laterally spaced to correspond with the spacing between bolts 32 for receiving these bolts. As also seen in Fig. 1, the tank portion 39 is located at the rear of bowl portion 42, with tank bottom wall 39a substantially below the bowl rim 42a. Moreover, the usual ball cock (not shown) operated by the usual float (not shown) will maintain the highest level of the body of flushing water within the tank portion 39 well below the rim 42a of the bowl portion 42. By employing such a low tank portion 39, the water level in the closet 7 will not rise suiciently high enough to 'overow the rim 42a even if the closet 7 is iiushed when lower stack 11, stack fitting 12 or outlet 43 are plugged up. As will be apparent, this prevents unnecessary and undesirable damage to property, as well as a situation detrin mental to personal health.

As shown in detail in Fig. 5, the connection between rear outlet 43 and elbow 13 of fitting 12 is made by a coupling 49, the reduced end of which slidingly lits within the mouth of elbow 13 and is sealed therein by an O-ring 50 recessed in the elbow.` The enlarged end of coupling 49 abuts a gasket 51 which fits within a cylindrical recess 52 formed within panel portion 44 and around outlet 43. The fitting between gasket 51 and the enlarged end of coupling 49 is made under pressure caused by set screws 53 which are adjustable in flanges 54 on elbow 13.

A typical installation procedure will now be described. The first step is to determine the location of lower stack 11, its center line being positioned a given distance, say 81/2 inches to the right of the closet center line (i.e. the center of rear outlet 43 as seen in Figs. 2 and 5) and a given distance, say 31/2 inches behind the finished Wall line (i.e. to the left of the outer surface of finished Wall 10 as seen in Fig. l). Following this, the lower stack 11 is then installed substantially to the height shown in Fig. 2, whereupon the floor slab 8 is poured. Next, the base plate 16 is centered on slab 8, 81/2 inches from the vcenter line of stack 11 and 31/2 inches behind the finished wall` line, whereupon thev location of the b'olt holes are marked and the slab drilled for the reception of anchor bolts 17 and levelling screws 55 (Fig. 1), which may be held in place by any suitable means such as VPhillips expansion shields 56.

4Following this operation, the elbow 13 and stack tting 12 are assembled in the usual manner, care being taken that the center line of the mouth of the elbow 13 and the center line of the fitting 12 are approximately 81/2 inches apart. The completed fitting 12 including elbow 13 is assembled With the base plateV 16 and uprights 19 in the usual manner, preferably by means of bolts 57 (Figs. 1, 2 and 5) passing inwardly through the right hand upright plate 19 and into threaded openings provided in lugs 58 formed on fitting 12.

At this point, base plate 16 and the fitting assembly are placed on slab 8 with the anchor bolts 17 projecting through the openings provided in the base plate, and the levelling screws 55 bearing against the bottom of the base plate. These screws are then adjusted to bring the mouth of elbow 13 to the correct roughing height. Next, the yoke supporting plates 20 are bolted to the base plate 16 and upright plates 19, `after which the plates 25 andV 26 are located in proper position (i.e. plate 25 being lsubstantially fiush with finished wall 10), and fastened in place by means of lock nuts 30, 31 on bolts 28. The assembled carrier is then bolted to the floor and secured Yin position by nuts 18 on anchor bolts 17. The joint between stack fitting 12 and lower stack 11 is then made up inthe usual manner, after which the upper stack 15 is likewise installed according to conventional practice.

y Prior to installing closet 7, the gasket 5.1 is winserted into recess 52 surrounding rear outlet 43 in the closet, and the coupling 49 is inserted within the mouth of elbow 13, the extent to which the coupling projects therefrom being properly adjusted by means of the set screws 53. The closet 7 is then lifted and tilted slightly so that the upper outer edge of lateral wall means 46 is located close to but does not contact wall l0` in order to prevent marring the 'finish thereof, anges 47 lie above lugs 27 and slots 48 are positioned over but slightly outwardly of bolts 32, in order to provide clearance for the enlarged end of coupling 49. The closet 7 is then slid downwardly, whereupon flanges 47 irst overlyingly engage lugs 27 and are cammed thereby into engagement between the lugs and plate 25. This camming action automatically causes slots 48 to swing back freely down over bolts 32 and recess 52 to enclose the enlarged end of coupling 49'. Just as the previously described upper fastening, bracket and flange means cause the upper portion of panel portion 44 to t substantially flush against wall 10, the lower portion of panel portion 44 is permitted to fit substantially flush against the finished wall by means of lock nuts 34 which have previously located the bearing washers 35 substantially flush with the finished wall It). The fiber washers 36 and cap nuts 37 are then drawn up over bolts 32 until the lower part of panel portion 44 does actually t flush against washer 35, and the gasket 51 is spread into tight engagement with recess 52 by the enlarged end of coupling'49 to provide the desired seal around outlet 43. As will be apparent, the installation of closet 7 on carrier 6 is facilitated by the improved design of these components, and can readily be performed with a minimum of effort and in a minimum amount of time as compared with the prior art installations described above.

Referring briey to Fig. 6, there is shown therein a typical back-to-back installation incorporating the features of the invention. procedure is the same as for the single installation illustrated in Figs. 1-5 with `the following exceptions. The carrier is modified by replacing the yoke supporting arms with a second pair of yoke upright plates 59 having lateral projections 60 secured to the inside of the irst pair of upright plates 19 by means of the bolts 24. In addition, the fitting 12 is provided with two pairs of internally threaded lugs 58, one pair on each side, for receiving bolts 57, and the elbow 13 is replaced by a T 6l to provide the proper plumbing connection for the opposed rear outlets 43 of the adjacent closets 7. This structure permits two identical closets 7 to be installed in backto-back relationship using conventional wall structure.

It will now be seen how the above described invention accomplishes its various objects. For example, the inventive installation is economical to manufacture, a typical carrier 6 beingprovided with the unique bracket means including plates and 26, while the tank, bowl and panel portions of the closet 7, including anges 47 and slots 48, are cast in one piece. The inventive installation is easy to install, as the carrier 6 lits within conventional wall structure and the closet is merely lifted, tilted and slid down into place so that flanges 47 fit between plate 25 and lugs 27, slots 48 fit over bolts 32, and recess 52 ts around coupling 49. The inventive installation is more pleasing in appearance, as the cumbersome separate bowl and tank portions are combined together with a panel portion which is of less width than the tank portion to form an attractive, streamlined one piece unit. The inventive installation is also practical, as it is equally adapted for use in either single or back-to-back installations for lower cost residential construction. Moreover, the use of the unique bracket means and the unique panel portion at the rear of the tank and bowl portionsV of the closet eliminates any undesirable puncturing of the tank portion, as well as eliminating at least two of the formerly exposed bolts for supporting the closet. This permits the The structure and installation.

@i use of a panel portion which nicely blends in with the decor of the tankand bowl portions, the two lower fastening means being the only evidence of support which is visible, but the location of which does not detract from the overall appearance of the installation. In addition, the low tank portion 39 effectively prevents the water in bowl portion 42 from overflowing the rim 42a even when the closet 7 is ushed while the soil or closet lines are plugged up, and thereby avoids undesirable conditions arising from such overflow.

While only a single and a back-to-back installation have been described herein as applied to a so-called slab construction, it is apparent that various changes and modifications may be made in the invention by those skilled in the art without departing therefrom, and it is to be understood that the scope of the invention is to be determined by the appended claims. For example, a socalled bar supported carrier, which is particularly adapted for wood frame type building construction, can be just as easily provided with the unique bracket means.
